Abstract Transvenous embolization emerges as a viable intervention for addressing intracranial dural arteriovenous fistulas (DAVF). Accessibility to the fistulous site via internal jugular vein (IJV) may be impeded by associated sinus apoplexy or thrombosis, prompting development of transcranial approach venous in such scenarios. The presented case details utilization DAVF. This method allows unobstructed entry DAVFs situated on superficial sinuses that lie beyond reach IJVs. efficacy this...

The aim of this study was to evaluate the radiation doses patients and staff received from first cases prostatic artery embolization (PAE) conducted in a public hospital Recife, Brazil. Five PAE procedures for 5 men diagnosed with benign hyperplasia were investigated. In order characterize patient exposure, dosimetric quantities, such as air kerma-area product (P KA), cumulative kerma at interventional reference point (Ka,r), number images, etc, registered. To possibility deterministic...

The purpose of this study was to evaluate patient and medical staff absorbed doses received from transarterial chemoembolisation hepatocellular carcinoma, which is the most common primary liver tumour worldwide. performed in three hospitals Recife, capital state Pernambuco, located Brazilian Northeastern region. Two are public (A B), one private (C). For each procedure, number images, irradiation parameters (kV, mA fluoroscopy time), air kerma-area product (PKA) cumulative kerma (Ka,r) at...

The aim of this study is to evaluate organ and tissue absorbed doses patients undergoing hepatic chemoembolization procedures performed in two hospitals the city Recife, Brazil. Forty eight fifty were investigated. For 20 cases with PA projection only, organs tissues dose KAP conversion coefficients calculated using mesh-based anthropometric phantom series FASH MASH coupled EGSnrc Monte Carlo code. Clinical, dosimetric irradiations parameters registered for all patients. maximum found 2.4...

Objective The present study was aimed at estimating the doses received by physicians and patients during cerebral angiography procedures in a public hospital of Recife, PE, Brazil. Materials Methods sample included 158 adult patients, following parameters were evaluated: exposure (kV, mAs), number acquired images, reference air kerma value (Ka,r) kerma-area product (PKA). Additionally, involved evaluated as for absorbed dose eyes, thyroid, chest, hands feet. Results results demonstrated that...

Abstract Prostatic artery embolisation (PAE) is used to treat patients with benign prostatic hyperplasia and lower urinary obstructive tract symptoms. It an interventional procedure which uses fluoroscopy equipment can result in exposure high doses of radiation staff. We aimed demonstrate the reduction received by staff during PAE implementing optimised protocol called Radiation Exposure Curtailment for Embolisation (RECiFE). This was implemented cooperation medical team technical using...

The aim of this study was to estimate brain radiation dose the main operator during interventional radiology procedures. Occupational doses from 19 procedures were measured using thermoluminiscent dosimeters and an anthropomorphic RANDO woman phantom simulating a operator. Results show that, radiologists may receive minimum maximum per procedure 0.01 mGy (left temporal cortex) 0.08 (temporal lobe cortex), respectively. A radiologist who works without movable shielding devices has typical...

Abstract Plastic and metal biliary stents can fail to function properly, such failure being due a positioning error or the migration, occlusion, fracture of stent. An obstructed stent act as nidus, causing complications recurrent persistent cholangitis. It also cause vascular (such bleeding formation pseudoaneurysms), perforate liver capsule (causing biloma abscess), or, in rare cases, intestinal obstruction perforation. In this pictorial essay, we demonstrate various interventional...

Introduction: Anesthetists play an important role during interventional radiology procedures. Like the main operator, anesthetists may also be subject to significant radiation levels in fluoroscopy suite. Due its complexity, hepatic chemoembolization procedures demand high fluoroscopic times and digital subtraction angiography images, exposing patients medical staff doses.
 Objetive: To assess quantify which one anesthetist was exposed over course of seven consecutive procedures,...

ABSTRACT Sub-arachnoid hemorrhage (SAH) promotes impairment of upper cortical functions. However, few information is available emphasizing changes in language after aneurismal SAH and aneurysm location influence. Objective To assess the verbal fluency performance pre- post-surgery patients caused by an anterior communicating artery (AcomA), left middle cerebral (L-MCA) posterior comunicating (L-PcomA). Methods Assessment 79 with SAH, on two occasions: post surgical treatment. They were...

Introdução: A literatura possui relatos de vários trabalhos com tratamento oclusivo artérias carótidas internas, forma temporária ou permanente, para tratar doenças tumorais e vasculares. Em relação às vasculares, o método reconstrutivo é muitas vezes melhor tratamento, pois permite a perfusão sanguínea carotídea. Porém, devido aos altos custos desses dispositivos, oclusão carotídea passar ser uma terapia eficaz útil quando possível.

Objective: Discuss cognitive deficits caused by subarachnoid hemorrhage (SAH) after rupture of cerebral aneurisms, since about half the patients have severe or at least striking declines in one more functions domain. Methods: This paper presents a literature review on secondary to aneurysmal SAH. There was no delimitation periods publications locality where it applied. The bibliographic references were accessed through database PubMed (http://www.ncbi.nlm.nih.gov/pubmed/). Results: are three...

Background: The purpose of this study was to compare the primary patency 7F vs 10F plastic biliary stents (PBS) placed by percutaneous transhepatic technique in two cohort patients that received palliative treatment for malignant obstruction. Materials and methods: From January/2016 April/2020, 34 who were admitted a tertiary academic center because obstruction enrolled prospective non-randomized study. Between December/2018, PBS implants performed between January/2019 January/2021,...
